Changed front brakes, and now I have......


a very loud squeaking noise. Like the brake is already gone, but it isn't. Espically when I start off and drive - it feels as if the calipar is stuck.

We took the wheel off, and spun the rotor around... it still squeaked, badly. Sprayed it down with brake cleaner ( I think that's what it's called) ... it quit the noise for a bit, then it started up again.

Any ideas?

And.. my second question is...

I got my windows tinted last saturday. Since then, my back wiper will not turn on. Does anyone have any idea what's wrong? A fuse blown? I'm sure he didn't cut it off while tinting, but ever since the windows got tinted it has not been working.

So, I'm not really sure.

I don't have a rear wiper so I can't help you there. But, sounds like a bad fuse, relay, switch or broken connection somewhere. Vague, sorry. Blame the tint person

Damn wiper switches must be made of gold and full of diamonds. If so, ebay/junkyard time.

Concerning the front brakes,
What brand brakes? Some brands just squeak.
Did you turn or replace rotors? If not, get better pads and get those rotors turned or replaced.
Here is a link with pictures of the brake hardware. I make an honest effort to always replace the hardware with a brake job. Missing or worn hardware can cause a squeak.

Brakes:

Did you fully compress the pistons when you installed the new pads and bleed the whole system???

Also did you use any brake anti-sqeek compound between the pad and the shim???

and is the shim bent in any way???

Rear wiper:
There is a connector up the strut that powers the rear wiper. Make sure it is not disconnected. Its pretty common for that connector and the connector for the rear dfrost to be disconnected when you have the rear window tinted.

deadrx7conv -

Brake brands: Some kind from Discount Auto Parts - Not entirely sure.

The rotors this time have not been turned, nor need to be replaced right now.

There is a slight squeak, but now it's just sounding more like rubbing against something than anything.

No, we did not bleed the system, I was not aware that you had to do that. Hmm.. I don't know if my dad fully compressed the pistons or not, I will need to ask him.

Yes, we used brake anti-squeak compound after looking at it on Friday. It would stop for a few, then start up again...but now, that I've come to realize it's more of grabbing onto something, or rubbing against something more than squeaking....

Not to be stupid, but what is the shim? Is it that dust blocker (I believe that's what it is) around the rotor?

Okay thanks for the information on the rear wiper.

Okay, if the pistons didn't get fully compressed the pad might be resting against the rotor too tightly. If that is the case, it will get worse when driving, until the pad can wear down enough. You can check this by removing the wheel after driving a short distance, and then trying to turn the rotor by heavy gloved hand. The rotor should turn smoothly, without binding at all.

The shim is the thin metal peice that sits between the brake pad and the pistons. The anti squeek compound should go between it and the pad. The compound won't be listed in the FSM, but is a very common thing to use when replacing the pads.

I bet you left off the little spring at the top of the pads. It helps keep them from rattling against the rotors.

As for the wipers, first make sure it's not unplugged. If it isn't, check the fuse and measure the voltage at the motor. 12V but no movement means bad motor (doubtful). If the motor tests fine, and the fuse is OK, then look at the switch.

Ah good call Aaron , if they haven't done many Japanese brakes before it is easy to forget that spring.
